41. For Christ to dwell in the heart is simply for the heart to know him; in other words, to understand who he is and what we are to expect from him—that he is our Saviour, through whom we may call God our Father and may receive the Spirit who imparts courage to brave all trials. It is thus that Christ dwells with us, in our hearts. Only so can he be embraced; for he is not an inanimate thing, but the living God. How does man lay hold of the Saviour in the heart? Not by embracing him intellectually. It is accomplished only by living faith. Christ will not permit himself to be received by works, nor to be apprehended with mental vision; he will consent only to be embraced by the heart. If your faith be true and on a firm foundation, you have and feel Christ in your heart and are aware of all he thinks and does in heaven and on earth—how he rules through his Word and his Spirit, and the attitude of those who have Christ and those who have him not.
42. Paul desires Christ to be efficacious in the hearts of his followers unto the full realization of the promises of the Word—liberation from sin and death, and assurance of grace and eternal life. It is impossible for the heart having such experience to be other than firm and courageous to oppose the terrors of the devil and the world. But the heart which has not yet arrived at this point is here advised what course to take, namely, to pray God for such faith and strength, and to avail himself of the prayers of others to the same end. So much in regard to faith; now follows the mention of love.
"That ye, being rooted and grounded in love."
